Hot chicks with swords! What more do you need? The series is set on a fictional medieval island where humans are plagued by something called Yoma, which are humanoid shape-shifters that feed on human beings. A mysterious organization, known coincidentally as The Organization, creates human-Yoma hybrids to help them kill Yoma for a fee. These female warriors wear special armored uniforms. The public refer to them as “Claymores,” alluding to their Claymore swords, or “Silver-eyed Witches,” due to their silver eyes.
